5.2.1 Mounting
The UUT can be attached directly to the shaker head using a 1/4-28 stud.
Adaptor studs and plates are available for mounting sensors with different size
mounting threads. See Table 2 below.
NOTE:
The stud or adaptor plate should be mounted finger tight only, not
exceeding 10 in-lb (112 N-cm) into the shaker head. Exceeding the
maximum torque may damage the shaker. It is recommended to use the
open end wrench when mounting sensors to stabilize the shaker
armature.

A specially designed angular plate is available for calibrating the 993B-7-M12 triaxial
accelerometer. This plate will excite all three axes simultaneously resulting in 0.57 g per
axis. See section 6.0.
5.2.2 Power ON/OFF
Turns on the shaker for approximately 90 seconds. The unit will default to the previously selected
options. To defeat the auto shutoff feature and enable continuous operation, hold down the
FREQ
button while turning the unit on. All three frequency LEDs will briefly illuminate to indicate the shaker
is in CONTINUOUS operating mode. The unit will now operate until the
ON/OFF
button is pressed
again. When the unit is turned off, it will revert to the AUTO-OFF mode.
